From: Bud Liviu-Alexandru budliviu@gmail.com
This operations should be generic as there is nothing Intel specific. This works well for NXP i.MX8 stream IPC ops.
We start by moving sof/intel/intel-ipc.c into sof/stream-ipc.c and rename the functions to be generic.
Notice that we use newly introduced snd_sof_dsp_mailbox_read instead of sof_mailbox_read, to make sure that we are not bound to existing MMIO memory access, and we allow platform to implement their own memory access routines.
